Doesn't matter how many eggs. Use a trivel or basket made for the instant pot.

Put in 1 cup of water, use either a trivet or basket. Yes you can stack eggs on top of the others.

Set on pressure cook for 5 minutes, place steam release handle on seal. I recommend setting a timer elsewhere.

Press the cancel button, move the steam release handle to Vent. Set a timer for 5 minutes. During this time fill a bowl of cold water from the tap.

Open the lid, with tongs place eggs into the cool water for 5 minutes or longer is ok.
